RESUMO

Orthotopic liver transplantation (OLT) is the preferred treatment for selected patients with hepatitis B virus (HBV)-related liver disease. This study aimed to (i) define long-term outcomes following OLT for HBV; (ii) to quantify the incidence of HBV recurrence (rHBV) as it relates to anti-HBV treatment; and (iii) to determine outcomes for specific patient subgroups. We performed a retrospective chart review of 738 patients undergoing OLT between 1985 and 2010 at seven US transplant centers and divided the patients into 3 eras, 1985-1994, 1995-2004, and 2005-2010, based on hepatitis B immunoglobulin and antiviral therapies. In Era 3, female gender (p = 0.002), recurrent hepatocellular cancer (p < 0.001), and retransplantation (p = 0.01) were significantly associated with worse survival on multivariate analysis. Survival at three yr was poor for all ethnicities in Era 1, but significantly improved for all except black Americans by Era 3. Era 2 data showed a continued increase in rHBV from five to 10 yr (16.6%, 26.2%). In conclusion, while OLT outcomes have improved because of combination antiviral and immunoglobulin therapy, women and black Americans may not have realized an equal benefit. The rate of rHBV is significant even 10 yr post-transplant with survival affected.

RESUMO

BACKGROUND: Lamivudine (LAM) has been shown to prevent de novo hepatitis B virus (HBV) infection in recipients of hepatitis B core antibody (HBcAb)-positive liver transplants (LT) but primarily in small studies with limited follow-up. METHODS: We conducted a retrospective cohort study of HBcAb+ graft recipients at our institution from October 1999 to August 2008. RESULTS: One hundred nineteen recipients without prior HBV were identified (median age, 54 years; 70% male), of which 62 received LAM. The median follow-up was 2.6 years overall and 5.3 years in the LAM group. Among LAM recipients, 44% were HBV naïve (HBsAb-/HBcAb-) at LT, of which 6% developed HBsAb+ and 3% developed HBcAb+ after LT. Eight percent developed de novo HBV: two recipients became hepatitis B surface antigen positive at 70 and 23 months and three experienced breakthrough with HBV DNA more than 2000 IU at 1 to 9 months after LT. Sixty percent (3 of 5) were HBV naïve. Four (6%) other recipients also had transiently detectable HBV less than 2000 IU, which did not require any changes to their prophylaxis regimen. When compared with recipients who received other nucleos(t)ide analogues, there was no difference in de novo rates: LAM 8% (5 of 62), adefovir 15% (5 of 33), tenofovir 0% (0 of 3), entecavir 0% (0 of 1), and 5% (1 of 20) for those not given prophylaxis (P=0.59). CONCLUSIONS: LAM monoprophylaxis was effective in preventing de novo HBV in the vast majority of recipients over long-term follow-up. Adefovir had a higher rate of de novo infections numerically, whereas tenofovir and entecavir had no cases and may be more effective, but this was limited by a small sample size.

RESUMO

Lamivudine has been shown to prevent de novo hepatitis B virus (HBV) infections in liver transplantation (LT) patients receiving hepatitis B core antibody-positive (HBcAb(+)) grafts, but it may produce long-term resistance. Adefovir dipivoxil (ADV) might be effective in preventing de novo hepatitis and resistance. A single-center, prospective trial was conducted with 16 adults (10 men and 6 women, mean age = 54 ± 11 years) who underwent LT with HBcAb(+) grafts between September 2007 and October 2009. After LT, patients were given ADV [10 mg daily (adjusted for renal function)]. No hepatitis B immune globulin was administered. At LT, all graft recipients were hepatitis B surface antigen-negative (HBsAg(-)), 38% were surface antibody-positive (HBsAb(+)), and 50% were HBcAb(+). The median follow-up after LT was 1.8 years (range = 1.0-2.6 years). All recipients had undetectable HBV DNA (<40 IU/mL) after LT until the end of follow-up. One recipient (6%) who was HBsAb(-) and HBcAb(-) before LT became HBsAg(+) after 52 weeks. One recipient was switched from ADV to entecavir for chronic renal insufficiency, and 19% of the patients had renal dose adjustments. There was a nonsignificant trend of increasing creatinine levels over time (1.2 mg/dL at LT, 1.3 mg/dL 1 year after LT, and 2.0 mg/dL 2 years after LT, P = 0.27). A comparison with a control cohort of LT recipients with hepatitis C virus who did not receive ADV showed no difference in the creatinine levels at LT or 1 year after LT. In conclusion, ADV prophylaxis prevents HBV replication in recipients of HBcAb(+) livers but does not fully protect recipients from de novo HBV. Long-term follow-up is needed to better determine the risk of de novo infection.
